Abstract
A refrigerant compressor includes a drive shaft, a pulley fixedly fitted on the drive shaft, over which is passed a torque-transmitting member for transmitting torque from an external drive source to the drive shaft, and a compression rotational member mounted on the drive shaft for rotation in unison with the drive shaft to enable compression of a refrigerant gas. The pulley has a rim in the form of a hollow cylinder, over which is passed the torque-transmitting member, a boss which is fixedly fitted on the drive shaft, and a support member connecting the rim and the boss. A breakaway portion is provided in the support member or the drive shaft for breaking to disconnect the torque-transmitting member from the compression rotational member when a load torque larger than a predetermined value is applied to the breakaway portion. A bearing is arranged on the pulley for receiving tension of the torque-transmitting member to thereby maintain the rim in a rotating state when the torque-transmitting member is disconnected from the compression rotational member by breaking of the breakaway portion.
